[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] Xen 2.0.1 / Xenolinux 2.6.9+drbd+heartbeat odd behaviour starting domU
Hi all I'm running a Debian Sarge dom0 on an IBM eSeries x330 server. When I fire upo the domU some interesting and inexplicable stuff is happening. I dont get any boot messages until getty is started, and networking is not being started randomly. It reports that the networking has already been started, however the interfaces are not configured when I log in. Usually stopping and restarting the domU fixes this problem, however I made a temporary work around by creating a script that reruns the network setup at s99 if it detects the interfaces were not configured the first time networking was started. I have run this exact domU issue on another dom0, a whitebox pentium 4, and it always starts correctly and displays boot messages right from the get go. This is with the same xen packages and the same configuration as the IBM server. The differences in configuration are hardware related: the IBM has a ServerWorks raid5 and the whitebox server has software Raid1 on intel ICH6 SATA disks. I should probably also mention that both servers are tied together using heartbeat and replicate the domU to each other using drbd. I was periodically getting late local heartbeats but this appears to have been eliminated after I added a second network interface for heartbeat to communicate over. Unless I am running into some kind of hardware dependant scheduler bug I cant see what could be causing this misbehavior only on the IBM... thats just sketchy. Once I've ironed out this glitch I'll publish a quick and dirty foundation HOWTO on how to set up failover clustering using xen and drbd, which aside from this odd glitch work perfectly together. Thanks in advance for any ideas Tom ------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.
